Appendix

1. Introduction

The Web Services Description Language Version 2.0 (WSDL 2.0)
[WSDL 2.0 Core Language]
provides a model and an XML format for describing Web services.
WSDL 2.0 enables one to separate the description of the abstract
functionality offered by a service from concrete details of a
service description such as "how" and "where" that functionality is
offered. This document defines additional message exchange patterns
(MEPs) to be used in WSDL 2.0 and are provided as examples of the
extensibility of WSDL 2.0. This document is the product of the Web
Services Description Working Group, but its contents are
non-normative.

These patterns were originally intended for inclusion in
WSDL Version 2.0 Part 2: Adjunct [WSDL 2.0 Adjuncts]. The Working Group
ultimately decided that including only those patterns which were
referenced by the bindings defined in that specification was
clearer for implementors and users, and resolved to publish these
remaining patterns separately as a Note.
